The US Department of Energy is developing long-distance optical quantum networks, establishing the need for commercial-grade photonic quantum light sources. There is a need to determine the optimal sources and information encoding schemes while the technologies are developed, possibly varying by application. Investigation of the merits of encoding schemes in parallel with commercial development of robust modules operating in the telecom band are of immediate use and interest. The overall goal of the Phase I project is to establish the feasibility of developing a high efficiency source of pulsed quantum states that enable hybrid discrete variable/continuous variable (DV/CV) processing using photons in the telecom band. AdvR will leverage its expertise in creating robust, compact, waveguide-based KTP modules by creating spontaneous parametric downconversion modules. The university partner UIUC (under the direction of Prof. Paul Kwiat) will combine AdvR’s module with a novel photon-subtraction technique for high- rate generation of quantum states, vital for CV information processing and other quantum networking tasks. AdvR will create a custom SPDC module operating in the telecom band. The module’s quantum properties will be characterized at AdvR and UIUC and it will be shown that these properties can be optimized for use with UIUC’s novel photon-subtraction method. UIUC will construct and characterize the novel photon-subtraction system. In addition to the quantum networking applications, these sources have broad applicability to the research community. For instance, distributed squeezed states are also a resource for enhanced quantum sensing. Further development in Phase II and Phase III will lead to a fully integrated, compact product.
